just plugged into my ecm scanner 2006 yukon xl denali

So, i have just been introduced to the world of "scanning". 30$ "elm327" bluetooth + free scan software and i was able to see that my engine with 1900 hrs on it and 330000klm (205000miles) is rock solid.

fuel trims perfect, left bank 3%, right bank 0.6%, all systems normal.

boy does that give me confidence that my wife and kids are not going to get stranded on the side of the road.

i was introduced to the concept of "scanning", i put quotes around it because its not really scanning...its more like watching real time sensor data, 2 weeks ago from watching this video:

My scanner won't connect to my ecm. I have an 06 Yukon denai xl and I tired two different scanners and none of them talk to my ecm.

15 amp fuse for cigarette lighter is working. The elm327 I think that's what's its called connects to my phone, but won't connect to the ecu. The scanner works on my 2014 Chevy traverse and my 2009 Ford escape

I have the 12v power, it just wont talk to the ecu. I believe their is an issue with these cheap scanners and J1850
